SpletsiRNA（小干扰RNA）、shRNA（短发夹RNA）和RNAi（RNA干扰）是密切相关的概念，指的是细胞利用RNA分子调节基因表达的一种机制。. RNAi 是发生在细胞中调节基因表达 … SpletThrough a mechanism known as RNA interference (RNAi), small interfering RNA (siRNA) molecules can target complementary mRNA strands for degradation, thus specifically inhibiting gene expression. The ability of siRNAs to inhibit gene expression offers a mechanism that can be exploited for novel therapeutics.

SpletIf you need long-term silencing shRNA is the most common way to go. If you start with siRNA and change to shRNA you are also introducing additional variables. These changes could be subtle,...
SpletOptimal gene knockdown is a requirement for successful RNAi using shRNA systems. Rational design of shRNA sequences has largely been based on algorithms developed with siRNA. While some siRNA design rules apply to shRNA, more refined shRNA design algorithms will likely improve target gene silencing for shRNAs in the future 13.
